Context

Endpoint analytics started with client-side filtering for fast iteration. As data volume grows, that model degrades quickly.

What Changed

APILens now uses:
  • backend-driven filters, sorting, and pagination
  • endpoint options API for filter dropdowns
  • short-lived bounded cache on frontend for responsive UX

Why This Works

  • predictable query cost at high cardinality
  • no giant payload transfer for table interaction
  • consistent behavior across search/sort/page states

Key Principle

Use client cache for speed, backend queries for truth.
